Had to remove my egr blocker plate, re-install kitty, go back to stock tune to pass smog in Kalifornia. IOH and True CAI passed inspection. I'm not much of a mechanic and don't really want to be playing this game every other year. If I leave the kitty on and the blocker plate off, will the tow tune on a Diablo Predator make any difference in my performance and mileage?

Signature custom tuning is pretty clean. It passes the tailpipe smog test here.

Did you need the cat for the visual inspection, or for the opacity test? IIRC, CA doesn't even test the exhaust yet?

Cat was for visual inspection. Everything is visual except a "snap test" for smoke and an OBD check for codes. Will OBD recognize a non oem tune?
